Texas Instruments BQ500412RGZT

The bq500412 is a Qi-certified value solution that integrates all functions required to control wireless power delivery to a single WPC1.1 compliant receiver. It is WPC1.1 compliant and designed for 12-V systems, or 5-V systems with an optional boost converter, as a wireless power consortium type A6 free positioning transmitter. The bq500412 the surrounding environment for WPC compliant devices to be powered, safely engages the device, receives packet communication from the powered device and manages the power transfer according to WPC1.1 specification. To maximize flexibility in wireless power control applications, Dynamic Power Limiting (DPL) is featured on the bq500412 when used with an optional boost converter from a 5-V input. Dynamic Power Limiting enhances user experience by seamlessly optimizing the usage of power available from limited input supplies. The bq500412 supports both Foreign Object Detection (FOD) and enhanced Parasitic Metal Object Detection (PMOD) for legacy product by continuously monitoring the efficiency of the established power transfer, protecting from power lost due to metal objects misplaced in the wireless power transfer field. Should an abnormal operating condition develop during power transfer, the bq500412 handles it and provides indicator outputs. Comprehensive status and fault monitoring features enable a low cost yet robust, Qi-certified wireless power system design.

The bq500412 is available in a 48-pin, 7-mm x 7-mm QFN package.
